WEFT-REPLE NISHING LO OM.

Specification of Letters Patent.

Patented Oct. 29, 1907.

Application filed December 31, 1906. Serial No. 350,142.

To all whom it may concern:

Be it known that I, Barnum l McGurxuss, a citizen ol the United States, residing at Worcester, in the county of Worcester and State ol Massachusetts, have invented cer ain new and uselul lmprovenn-nts in :elt-Pteplenishing Looms, ol which the lollowing is a specification.

My invention relates to welt replenishing looms which have a magazine for the bobbins or lilting carriers, and lilling detecting means to indicate, on the substantial or practical exhaustion ol filling, tor the insertion of a new bobbin into the running shuttle, and my invention particularly relates to looms ol the class rclerrcd to having a center titling or welt stop motion, or a filling or welt stop motion at the central portion of the lay, which acts to stop the loom whenever a filling or welt thread breaks.

In welt replenishing looms ol the class rrlcrred to, when a new bobbin is inserted in the running shuttle, and the shuttle is picked lrom the magazine end of the loom to the opposite end ol the loom, and the end ol the filling thread is held by any ordinary holding means connected with 'the magazine, to have the shuttle properly threaded, the new titling thread, in its pa through the shed, may take a position near, and parallel to the reed line oi the lay, and near thehppcr part, ol the reed, so that although the lay and reed will beat up the filling in the proper way, the thread lork ol the center filling stop motion ordinarily used, will not reach and touch the filling thread, but as the lay beats up, the filling lork will pass under the tilting thread and not be engaged thereby, and will consequently drop down into its operative position, and act to stop the loom, in the same manner as it there had been no filling laid in the shed, or as it the titling was ln'oken.

The object oi my invention to prevent the action of the filling lork ol the center stop motion to stop the loom in the manner above described, and more particularly to provide means lor moving the filling or Welt thread ahead of the reed as the lay beats up, to carry it under the fingers ol the lilling fork, and pre vent the dropping down oi the fillin lork into its operative position to stop the loom, in case the filling or welt thread remains intact, when a bobbin is inserted in the running shuttle, and the shuttle is picked ll'OIil the magazine end of the loom to the opposite end of the 100111.

In my improvements, I provide means [or moving the filling or Welt thread ahead ol the reed as the lay beats up for the purpose stated, which means prclcrably consists of a blade or lork, located near the weft replenishing end of the lay, to positively engage the end of the filling thread alter the shuttle, with a new inserted bobbin therein, has been picked from the shuttle-box at the magazine end of the lay, and carry said thread toward the lront ol the loom, as the lay beats up, and under the lork or welt lingers ol the center stop motion, to prevent the dropping down ol said lingers and the operation thcreol, to stop the loom.

l have only shown in the drawings a detached part ol a welt replenishing loom, having a magazine of the Northrop type shown and described in U. S. lietters Patent No. 529,940, and a center lilling stop motion, or a lilting stop motion at the central portion ol the lay, with my improvements applied thereto, sullicicnt to enable those skilled in the art. to understaml the construction and operation thercolf llelerring to the drawingsI- l igurc l is a plan view ol detached parts ol a welt replenishing loom ol the class relerred to, at the magazine end thcreol, with my improvements applied thereto, and, l ig. 2 is a section, on line L, 2, l ig. I, looking in the direction ol arrow (1, same figure, the broken lint s show a dillercnt position ol some ol the parts.

hr the accompanying drawings, l is the loom side or end lrame, 2 the breast beam, 3 the lay, -11 the lay sword pivotally mounted at; its lower end on a stud 5, t) is the reed carried on the lay, 7 the hand rail, S the stationary shuttlc-box on the magazine end ol the lay, E) is the crank connector to the crank shall; 10, ll is the bottom shalt driven lrom the crank shalt 10 in the usual way, through gears, not shown. '12 the magazine, in this instnncool the above mentioned Northrop type, and located at the right hand ol the loom, 13 are the bobbins or lilting carriers held in the magazine, and having tilling 13 thereon; it is the operating arm ol the transl'errer mechanism, having the projecting end '14 adapted to be moved into the path ol the dagger 15 on the lay. The operating arm ht is last on a rock shalt 'l (3. An arm '17 last. on therock shalt it; is connected bya link 18 with an indicator lover 'l t]. 20 is a holding lever tor a bobbin or titling carrier, actuated by a spring 2t. 22 is the center filling or welt lork ol the center titling or welt stop motion. The lork 22 has in this instance lour lingers, and is located at the central portion of the lay 3. All ol the above mentioned parts may be of the usual and well known construction in the class of looms relerred to.

1 will now describe my improvements.

At the lront of the lay 3, near the magazine end of the loom, and near the inner open end ol the stationary shuttle-box S, is in this instance secured, on the lront oi the lay beam, a stand 23, having in this instance at its upper end the hub or bearing 22% lor a rocking pin or stud 2 t, which is loosely mounted in said hub. On one end ol said rocking pin or stud 21 is secured, in this instance a small block or collar 25, to which is attached one end of a blade or linger 26, which in its lowered position is adapted to enter a transverse recess 3 in the upper sin-lace ol the lay beam 3, see Fig. 1, leaving the upper surface of the lay beam clear when the shuttle is picked.

Fast on the pin or stud 24 to rock therewith, is, in this instance, the hub 27 on one end of an arm or link 27; the other arm of said arm or link 27 has a pin 28 thereon, to loosely receive the hub 29 on the upper end of a connector or rod 29, see Fig. 2. The lower end of the rod or connector 29 is adjustably connected with an elongated slot 30 in one end of a lever 30, which has the hub 30 pivotally mounted on a stud 31 secured to the loom frame. The other end of the lever 30 has in this instance secured thereto, by a bolt 32, one end of an arm or lever 33, having foot or engaging surface 33 thereon, which extends in the path of and is adapted to be engaged by a cam 34; fast on the bottom shaft 11, see Fig. 2. The arm 33 may be vertically adjusted.

' Through the rotation of the bottom shaft ll and the cam 34 thereon,-and connections to the pivotally mounted blade or finger 26, a pivotal movement is communicated to said finger at-regular predetermined intervals, to move said blade or tingerZG down into the recess 3 in the upper surface of the lay beam 3 on the backward movement of the lay, and hold it there while the shuttle with a new inserted filling is being picked from the shuttlebox under the magazine, and after the shuttle has been picked from said shuttle box, and as the lay beats up, said blade or finger 2G is raised to engage the filling or weft 13, and move it towards the front of the loom, ahead of the reed 6, as shown by dotted lines in Fig. 2, and consequently carry it under the fork or fingers 22 of the center filling stop motion, to prevent said fork or fingers from dropping down and putting into operation the stop motion to stop the loom.

It will be understood that the details of construction of my improvements may be varied if desired, and they may be adapted to be used on weft replenishing looms having center filling or-weft stop motions, with magazines, or weft replenishing means of different constructions.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a weft replenishing loom having a center filling stop motion, means located at one end of the lay, and carried on and moving with the lay, to move the filling ahead of the reed as the lay heats up; andcarry the filling under the fork of the center filling stop motion.

2. In a weft replenishing loom having a center filling stop motion, means for moving the filling ahead of the need as the lay beats up, to carry the filling under the fork of the center filling stop motion, said means comprising a blade or fork mounted on the lay at the weft replenishing end thereof. and moving with the lay, and means for mov in: said blade or fork.

33. In a weft replenishing loom having a center filling stop motion, the combination with the lay, of means at one end of the lay and carried on the lay, to engage the filling near the end of the lay, and move the filling ahead of the reed as the lay heats up, to carry the filling under the fork 01' the center filling stop motion.

4. In a weft replenishing loom having a center filling stop motion. the combination with the lay, of a blade or fork carried on the lay at the weft replenishing end thereof, and means for moving said blade or fork tocause it to engage and move the filling or weft thread to carry it under the fork of the center filling stop motion as the lay heats up.

In a weft replenishing loom having a center filling or weft stop motion, the combination with the lay having a transverse. recess therein for a blade or fork, of said blade or fork carried on the lay at the weft replenishing end thereof, and means for moving said blade or fork to cause it to engage and move the filling or weft thread to carry it under the fork or fingers of the filling stop motion as the lay heats up.
